The key to a happy marriage? Kristen Bell has you covered

Kristen Bell and Dax Shepard have always been super-candid about how and why their marriage works. They're open about how sometimes they go through rough patches. They're open advocates for couple's therapy, even when things are going well. We love them because they don't sugarcoat their marriage — they let everyone know they fight and struggle and things aren't perfect and that's totally OK.

Needless to say, we should all be lining up for marriage advice from these two, because after a decade, they seem to have this thing nailed. So when a fan wrote to Bell asking for advice for his friends who were about to get married, she delivered, and we are all listening up.

"I wrote something congratulatory but then thought 'Kristen! Wait! You are an old married woman, shouldn't you have some wisdom to share?!' After I was finished I realized what I wrote is pretty much the A-Z of how @daxshepard and I keep our relationship healthy. Its worked for us so far, So here ya go," Bell wrote on Instagram, alongside the handwritten note containing her best advice for a happy relationship.

And it is solid advice, fam. Among the things she recommends: Be vulnerable with your partner, always. Take time apart when you need it. Be happy when your partner is happy.

"In 10 years, when the dopamine has waned, remember: Life is a crazy ride. It's a privilege to go through it with a partner," Bell writes in one particularly touching part. She ends her note with, "Know that everyone is doing the best they can with what they've got. So get a bigger emotional tool box to fix your problems."
